On solving the provided question, we can say that the provided slope is -2/3 equation of line 2x + 3y -7 = 0

A line's slope determines how steep it is. A mathematical equation for the gradient is called "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical change (rise) between two points to the horizontal change (run) between those same two spots. When a straight line's equation is written as y = mx + b, the slope-intercept form of an equation is employed to express it. The y-intercept is located at a location where the line's slope is m, b is b, and (0, b). For instance, the slope of the equation y = 3x - 7 and the y-intercept (0, 7).The line's slope is m. b is b at the point where the y-intercept is, and (0, b). As an illustration, the equation y = 3x - 7 has a slope of 3, and its y-intercept is (0, 7).

the provided slope is -2/3

let us assume x1 = 2 and y1 = 1

equation of line =>

y-1 = -2/3(x-2)

y-1 = -2x/3 + 4/3

Answer: The statement that is true about the function f(x)=4x-4 is:

It is a linear function, as it is a straight line in the form of y=mx+b where m is 4 and b is -4

The y-intercept of this line is -4, which means when x=0, y=-4

The slope of this line is 4, which means for every 1 unit increase in x, y increases by 4 units

The domain of this function is all real numbers and the range is all real numbers except -4

The equation of the line is y = 4x - 4

The graph of this function is a line with a slope of 4 and y-intercept of -4.

B. c = 15.9 + 12(2025 - 2014)

C. 147.9 gigabytes

D. Unsure what you meant

Step-by-step explanation:

A. In this equation, 'c' represents the flash storage capacity in year 'y' and '15.9' is the flash storage capacity in year 2014. '12' represents the yearly increase in storage and '(y-2014)' represents how many years have passed from 2014.

For loop is a type of looping structure that is used in programming to repeat a sequence of codes until a certain condition is met.

In mathematics, a function is a relation between a set of inputs and a set of outputs, such that each input is related to exactly one output. Functions are often represented as mathematical expressions, or as a graph or table. The input to a function is known as the argument, while the output is known as the value. Functions are used to describe physical phenomena, and to model relationships between different variables.

It is commonly used to go through each element in an array or a list without having to write the same code multiple times. For example:

// Initialize array
int arr[] = {1, 2, 3, 4, 5};

// For loop to print out each element in the array
for (int i = 0; i < 5; i++) {
 System.out.println(arr[i]);
}
In this example, the for loop will print out each element of the array until it reaches the condition that i is less than 5, which is the length of the array.

The number of pair of sunglasses that the company needs to sell in order to make profit is 80,000.

In economics, business, and especially cost accounting, the break-even point is the point at which total cost and total income are equal, i.e. "even". There is no net loss or gain, and one has "broken even," despite the fact that opportunity costs were incurred and capital got the risk-adjusted, expected return.

In order to make profit the organization needs to be at breakeven. Therefore, firstly they need to make profit that is equal to the refurbish cost.

The Profit on per pair of glass =  Selling price per pair - Labor and material cost per pair - marketing cost per pair

The Profit on per pair of glass =  $99 - $30 - $19

The Profit on per pair of glass =  $50

Now, the breakeven point can be found as,

Break even quantity = Refurbish Cost / Profit on a pair of sunglasses

                                  = $4,000,000 / $50

The current sum of their ages is 40. In 10 years, 10 will be added to each of their ages, so the sum will be 60.

At that time Lisa's age is 3 times Myra's age, so will be 3/(3+1) = 3/4 of the total.

  Lisa's age in 10 years = (3/4)(60) = 45

xo = (x1 + x2)/2

yo = (y1 + y2)/2

The probability that on any one day, Heila will not be late for school is 0.69 or 69%.

We can use conditional probability to find the probability that Heila will not be late for school on any one day.

Let W be the event that Heila walks to school, and L be the event that Heila is late for school.

We know that:

P(W) = 0.65 (the probability that Heila walks to school)

P(L | W) = 0.4 (the probability that Heila is late for school given that he walks to school)

P(L | W') = 0.1 (the probability that Heila is late for school given that he cycles to school)

The probability that Heila is not late for school is the complement of the event that he is late for school. So:

P(L') = 1 - P(L)

We can use the formula for conditional probability to find the probability that Heila is not late for school:

P(L' | W) = 1 - P(L | W) = 1 - 0.4 = 0.6

P(L' | W') = 1 - P(L | W') = 1 - 0.1 = 0.9

We also know that the total probability of the outcomes must be equal to 1. Therefore, we can find the probability that Heila walks to school, P(W) by using the following equation:

P(W) + P(W') = 1

We know that P(W) = 0.65, so we can find P(W') by subtracting P(W) from 1:

P(W') = 1 - P(W) = 1 - 0.65 = 0.35

Now, we can use the formula of Total Probability to find the probability that Heila will not be late for school:

P(L') = P(L' | W) * P(W) + P(L' | W') * P(W')

P(L') = 0.6 * 0.65 + 0.9 * 0.35 = 0.69

Therefore, the probability that on any one day, Heila will not be late for school is 0.69 or 69%.

Step-by-step explanation:

The input variable is "Height," while the output variable is "Weight."

A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable.

The cause is the independent variable. Its value is unaffected by the other study variables. Effect is the dependent variable. Changes in the independent variable affect its value.

When doing an experiment, the independent variable is what you alter, and the dependent variable is what changes as a result of that change. This is an easy way to conceive of independent and dependent variables. The independent variable can alternatively be viewed as the cause, and the dependent variable as the result.

The input and output variables are "Height" and "Weight," respectively.

Detailed explanation:

"Weight and height are related"

As we all know, the independent variable in a function of the form y=f(x) is x, and the dependent variable is y.

In other words, after substituting the values of "x," we are getting the values of the quantity "y."
